What is the difference between DC and DCC?
A. With a DC (analogue) system you apply power to the track when you want to move a locomotive. With a DCC system all of the track is live all of the time, so you can drive more than one train at a time on the same track. This does have its problems! There are ways around these problems, though, as you will see below. Each locomotive is controlled by the use of a decoder. This device allows additional features such as sound and lighting to be controlled through the electronic pulses that travel through the rails. In addition you can control points and signals from the DCC controller, or from a computer if you want to link the system into a PC.
